The purpose of this paper is to provide a metric for validating the Nationwide Suspicious Activity Reporting (SAR) Initiative’s (NSI) sixteen-category instrument, which is designed to guide law enforcement in the collection and analysis of suspicious behaviors preceding serious crimes, including terrorist attacks.

Data on suspicious preoperational activities and terrorism incident outcomes in the USA between 1972 and 2013 come from the American Terrorism Study (ATS). Using a mixed-method approach, the authors conduct descriptive and multivariate analyses to examine the frequencies of the least and most prevalent suspicious activities (or SAR indicators) and how they predict the likelihood of terrorism prevention. In addition, the authors contextualize how configurations of SAR indicators are associated with the successful thwarting of terrorism incidents by law enforcement using an analytical method known as conjunctive analysis of case configurations (CACC).

The study reveals several key findings. First, certain behaviors categorized as suspicious, such as making threats, occur more frequently than others. Second, making threats, conducting surveillance and terrorist recruitment/financing predict law enforcement interdiction in terrorism plots, while misrepresentation (or the manufacturing and use of false documents) is more associated with terrorist success. Third, prevalent SAR indicators operate differently in the context of various combinations of suspicious activities to shape the likelihood for law enforcement interdiction.

The current study’s findings may not be generalizable to other forms of violent extremism and terrorism outside of the USA.

This study illuminates opportunities for the NSI to provide law enforcement with the necessary tools to reduce terrorism risk and prevent future attacks.

To our knowledge, no scholarly work to date has assessed how observable behavioral indicators of suspicious preoperational activities affect the outcomes of terrorist plots.

In this chapter, we provide a brief historical framework of the events and policy changes that impacted the prosecution of terrorism over the past 50 years with emphasis placed on the changes that resulted from the 9/11 attacks.

We provide a review of relevant literature and complete the chapter by providing new data (2015) on case outcomes derived from the American Terrorism Study, a database housed in the Terrorism Research Center in Fulbright College, at the University of Arkansas.

Investigative and prosecutorial authority in U.S. terrorism cases has experienced ebbs and flows that correspond with terrorism attacks as well as missteps by the FBI, and each has impacted the success of prosecution efforts. Despite dramatic changes, the number of cases prosecuted after 9/11 is unprecedented, and conviction rates continue to climb.

This chapter provides the reader with a synopsis of the policy changes that have occurred in federal terrorism investigations and trials from the late 1960s upto the present. Based on that context, we provide an explanation of how those policy changes have impacted terrorism prosecutions.

Research on the link between tourism and politics still remains relatively underdeveloped and more so when one considers the link between this phenomenon and the study of elections or psephology. This is despite the importance of elections to the democratic process and to considerations of the distribution of scarce resources particularly in countries heavily dependent on tourism. This chapter seeks to address this lacuna in scholarship through a theoretical explication of the nature of political issues and voter response. Applied to the development of a possible research agenda, this would aid in exploring the salience of tourism within electoral agendas from a relational perspective.

In this chapter, we examine several attributes of lone wolf terrorists and how their activities are temporally and geospatially patterned. In particular, we demonstrate how precursor behaviors and attack characteristics of lone wolves are similar and different compared to those of group-based terrorists.

Based on data drawn from the American Terrorism Study (ATS), we examine 268 federal terrorism “indictees” linked to 264 incidents. Three types of loners are identified based on group affiliations and levels of assistance in preparing for and executing terrorist attacks. A series of analyses comparatively examine loners who had no assistance and those actors that did.

The results of this study suggest that lone wolf terrorists are more educated and socially isolated than group-based actors. Lone wolves also engage in less precursor activities than group actors, but are willing to travel greater distances to prepare for and execute attacks. Explanations for why lone wolves are able to “survive” longer than terrorist groups by avoiding arrest may in part stem from their ability to temporally and geospatially position their planning and preparatory activities.

Studies on lone wolf terrorism remain few and many are plagued by methodological and conceptual limitations. The current study adds to this growing literature by relying on lone wolf terrorism data recently made available by the American Terrorism Study (ATS). Our findings are valuable for members of the law enforcement and intelligence communities responsible for the early detection and prevention of lone wolf terrorism in the United States.

Depending on the research approach one uses, the development of particular bodies of knowledge over time is the result of a combination of agency, chance, opportunity, patronage, power, or structure. This particular account of the development of geographies of tourism stresses its place as understood within the context of different approaches, different research behaviors and foci, and its location within the wider research community and society. The chapter charts the development of different epistemological, methodological, and theoretical traditions over time, their rise and fall, and, in some cases, rediscovery. The chapter concludes that the marketization of academic production will have an increasingly important influence on the nature and direction of tourism geographies.

Travel and tourism have had a long history in the Nordic countries, but research on tourism has a relatively short tradition in the region. Recently, academic interest in the Nordic tourism space has grown and diversified especially as a result of increasing numbers of academics and institutions involved with tourism geographies and studies and education in the region. The Nordic context has provided thematic focus areas for empirical studies that characterize tourism geographies in the region, with topics including nature-based tourism, utilization of wilderness areas, second-home and rural developments, impacts in peripheries, and tourism as a tool for regional development. In addition, there are emerging research themes outside of the traditional core topics, such as urban, events, and heritage tourism.

This chapter aims to familiarize the reader with some of the important aspects of tourism geography in the German-speaking countries. It starts with a primarily historical-genetic perspective on tourism development and the theoretical traditions associated with them. The second section describes the structure of the discipline, with a focus on the institutionalization of the field in the universities including their research specialization. The chapter maintains that tourism geography plays a marginal role compared with other subdisciplines of geography, though this is reflected primarily in its institutionalization and less so in the research undertaken. The last section deals with the current challenges and future prospects in German-speaking geographies of tourism from a problem-centered perspective.
